I think the difference is the Guatemalans actually want help, and are appreciative of it.Yeah, I hear all the time about mission trips to south america. My vote would be for them to solve the homeless/hungry problem here and then move on to Guatemala.
I take it a lot of people on this thread haven’t spent much time in spitting distance of the people they’re claiming want help, but if you want to become jaded there’s plenty of places that will let you volunteer or even pay you.
